In the following question two equations numbered I and II are given. You have to solve both the equations and Give answer
I. 2x + 3y = 14
II. 4x + 2y = 16
A) X > Y
B) X \( \Large \geq \) Y
C) X < Y
D) X \( \Large \leq \) Y
Correct answer:
C) X < Y
Description for Correct answer:
I. 2x + 3y = 14
II. 4x + 2y = 16
By equation I \( \Large \times \) 2 - equation II \( \Large \times \) 3, we have
4x + 6y - 12x - 6y = 28 - 48
=> -8x = -20
=> x = \( \Large \frac{20}{8} \) = \( \Large \frac{5}{2} \)
From equation I,
2 \( \Large \times \frac{5}{2} \) + 3y = 14
=> 3y = 14 - 5 = 9
=> y = \( \Large \frac{9}{3} \) = 3
Clearly, x < y
